A congenital nevus is a proliferation of benign melanocytes that is either present at birth or develops shortly afterwards. Congenital nevi are usually classified by size: small (less than 1.5 cm in diameter), medium (larger than 1.5 cm and up to 20 cm) or giant (measuring 20 cm in diameter or larger).
Scoliosis is a common condition related to syringomyelia in children; in fact, some studies have shown that more than 50% of children with a syrinx have abnormal spinal curvature.coliosis can be caused by congenital conditions, neurological conditions (like SM), or can be of unknown origins. 80% of scoliosis cases have an unknown cause and are labeled idiopathic. Treatment options include observation, bracing, and surgery.
Syringomyelia is a rare disorder in which a cyst forms within your spinal cord. As the cyst, which is called a syrinx, expands and lengthens over time, it compresses and damages part of your spinal cord from its center outward.Damage to the spinal cord caused by a syrinx can cause symptoms like progressive pain, stiffness, and weakness in the back, shoulders, arms, and legs.yringomyelia can develop as a complication of trauma, meningitis, hemorrhage, a tumor, or arachoiditis. Arachoiditis is a progressive inflammatory disorder that affects the arachoid or middle membrane that surrounds the brain and spinal cord.
